Use tomllib over toml for Python 3.11+

The uiri toml implementation doesn't support some minor features of TOML, such as "Not a homogeneous array".

Given that tomllib is added to Python's stdlib, and supports the above feature, it should be loaded by default, and uiri's toml lib should be loaded as a backup
